'ToaZZ whom it may concern:

lie it known that L'Fnnnnron A. JAoKsoN, .a citizen of the United States, and-a resident ofIdaho Falls, inthe county of Bonneville and State ofldaho, have made certain new and useful Improvements. in Beet-Harvesters, of which the following isra specification.

My invention is an improvement inrheet harvesters and-has for its objectto provide in a harvester of the character specified, a crowning and topping device having means for crowning the beets-and for delivering the tops to one-side of the machine.

In-the drawings: Figurel is-aside view of theimproved harvester, Fig. 2 is a top plan view,.Fig. 3 is an enlarged detail sectional view of the crowning mechanism, taken substantially on the line 33 ofFig. 2,an'd Figs. 4 and 5.-are sections on-the line 4-4: and 55= respectively, ofFig. 3.

(The present embodiment of the invention comprises-a frame consisting of side plates 1,- each of which is ofiset inwardly at its front endas-indicated at 1, and the said front ends of the plates-are connected to the arms 2 of a substantially- U-shaped bracket,

4 thesaid bracket comprising the said arms 2 and .a body 3. Each of the arms.2 is provided at its lower end with-a lateral. outwardly extending spindle 4 and a wheela is journaled on each spindle.

A clevis 6 is connected with. thebodyof tho bracketby means of a bolt 7. A draft -.apparatus 8, in the present instance-double trees, is pivoted to the clevis as indicatedat 9. -\An axle 10- is jounnaled transversely of the rear ends of the plates 1' inbearingsll,

and wheels 12 are secured to theends of the axle and are held in place by pins 13 or the like. The plates 1 are connected intermediate their ends bya cross bar 14, and ashaft 15 is journaled in the said plates'ia nd. transversely thereof near the bracket 2?3.

Arms 16-and 16- are pivoted on theshaft, eachrarm adjacent to one of the plates. 1-1 and on the inner side thereof, the arms being held in place with respect to the plates ,by means of collars 17. Each of thearms 16 is provided at its rear end with-an are shaped .portion 18, and second-arms 19-.and 19*v respectively, are adjustably connected with each of thearms Hand 16 intermediate the are shaped portion 18. and the shaft- 15.

Eachof the arms 19, 19 is provided at its free end witlnan are shaped portion 20, and

each of thesaid arms 16, 16 and 19, 19 is reduced in width from the commencement of .the-said portion to the free end thereof. .Each of the arms 19 and 19 is provided with anlongitudinally extending series of openings 21 at the end remote from the are shaped ,portion, and a bolt 22 is passed through one of. the said openings and a reg isteringopening in the arm 16 or 16, and is engaged by a nut to adjustably connectthe .said arm to the arm 16 or 16.

.A. transversely curved blade 23 is secured to the are shaped portions of the arms 16 and 16, and on the concave edges thereof nbyumeans. of rivets 2 1 or the like, and another blade 25 is secured. to the are shaped portions ofthe arms 19 and19, the said bladebeing on the concave edges of the ..f 1l'ms,.and secured thereto by rivets 26 or the It will be noticed from an inspection of Fig. 2 that the body portion of the arm 16 isof greater length than the body portion of .the arm 16, so that the-arc. shaped portion thereof is in rear of the are shaped portion of the arm.16. Thus. the blade 23 will be inclined with respect to the direction of motion of the-machine. The arms 19 and 19*? are spaced apart from the are shaped portions of the arms 16.and 16 the same dis- -tancesor that. the blade 25 is inclined in the.

samemmanner, as the blade 23. The cutting edge of the blade 23 is spaced below the free :edge of the blade 26, so that when the said blade 23 crowns the beets while they are still in the ground, the crowns will pass upon the concave surface of the blade 23 to the rlght .of themachine, where the tops and crowns will be delivered at one side of the row. By means of mechanism to be 7 presently described, the crowning device may be ad uSted to crown the beets at any desired point. At the end of the crowning device remote ,from the point of delivery, a toothed wheel ,or colter 27 is supported, the said colter being journaled on a journal pin 28 at the ,lower end of a stock or standard 29 ad- ,justably connected with the arm 16. The

stock or standard is provided with a lon- ,gitu dinal series of openings 30 and a bolt 31 is passed through one of the said openingsand a registering opening in the arm to and a registering opening in the arm to connect the stock or standard, to the arm. .The engaging end of the toothed wheel 27 is below the cutting edge of the blade 23, and the toothed wheel removes a portion of the tops during the crowning operation.

It will be noticed from an inspection of Fig. 5 that the arms 16 and 16 are mortised on one face or grooved transversely, as indicated at 32 to receive the arms 19 and 19*, the mortising or grooving insuring that the arm 19 will bear the same angle'with respect to the arm 16 or 16 at whatever point the said arms may be connected. As shown in Fig. 4, the standard 29 of the toothed wheel 27 is mortised or grooved transversely, as indicated at 33 to receive the arm 16, this being for the same purpose as specified for the groove 32. The journal pin 28 is a bolt, which is passed through the hub of the wheel 27 and an opening in the standard and is engaged by a nut 34 to hold the parts in place.

The crowning device is adjusted, by means of an elbow lever 35, 36, the said lever being pivoted at 37 to one of the side bars 1-1. The arm 35'of the lever is provided with latch mechanism 38 coeperating with a toothed quadrant 39 secured to'the frame and the arm 36 of the elbow lever is connected to the arm 19 of the topping device by means of a link 40. When the latch mechanism is released, the arm 35 of the lever may be swung to raise or lower the topping mechanism. In rear of the crowning and topping mechanism is arranged the lifting mechanism for the beets for removing them from the ground.

A seat 87 is connected to the cross bar 14 of the frame, by means of a spring plate 88, and the said seat is arranged adjacent the lever 35.

In operation, the machine is drawn through the field in any desired manner, and with the members of the pairs of wheels 5 and 12 on op osite sides ofthe row. The crowning an topping device is adjusted to crown the beets at the proper point, and as the machine advances the cutting edge of the blade 23 removes the top and the crowns and they are passed outwardly to the right of the machine. The

toothed wheel 27 removes the superfluous- I claim 1. In a beet harvester, the combination with a wheel supported main frame, of
